ST. PAUL, Minn. - A search warrant affidavit says a Minnesota man accused of killing a 9-year-old boy by firing at passing cars told investigators he did it because people had been waking him up by revving their engines.
The St. Paul Pioneer Press reports that police found a note in Nhan Lap Tran's bedroom when they arrested him after the February rampage that read: "Random Kill, Fake Plates."
The affidavit filed in Washington County District Court says the date "12/12/12" was also scrawled on the bedroom walls.
Tran's attorney, Susan Drabek, did not immediately return a phone call to The Associated Press for comment Saturday.
The 34-year-old Tran is charged with six felonies in the Feb. 11 rampage.
Prosecutors say Tran had previously admitted to the shootings but hadn't given a motive.
